ALKING To all whom it bone-em Be it knowntha't I, PINCUS Furs,- a citlzen of the United States and a resident ofthe' city of Saginaw,' county of Sagin aW,'-State -of'D/I1chigan,have invented a new-end useful Improvement in Ta1king'Machine's,' of which the following isespe'cification.

My invention relates to talking machines of the disc record type and has fo'r its object, to provide adevice which will be siiiipl'e and economical'of constrii'ctiomthe movable part ofw'hich Will befliglit in Weight in order that it may not impose too" great amount of dragon the reproducingstylus.

A fuither'objeot is toprevide means can riedby thefto'ne-arm for operating 'an auto matic sto a for ai'i'estin the movement of the I a V I c tiirntible.

A further objectis ,to provide it lockbe'inoreifiilly set forth hereinafter; the inVen-'- tion consists in the novel construction, Combiniitionofelement's; and arrangements of parts Which'wiilflbe exemplified intheponstructio'n hereinaiftei" described in the specificationand illustintedin the accompanying drawings considered together or separately.

The inventive idea, involved is-ca'pzibiebf reeeiv'ing a; rarie ty of mechanical expressions, one of which "for the plilPQSBOf'liiLiS- tinting-the inVenti0n3'issh0Wii inthe acompanying drawings.

Mounted on diametrically opposite pivot points 17 in the gimbal ring is the inner end of a tone-arm member 18, the outer end of which supports a sound box orreproducer 19. The pivot points 17 are I fixed to the gimbal ring 7 in a similar manner as the points.8 are in the elbow tube. The inner end of the tone-arm member 18 is spherical, as is the gimbal ring, to allow for movement of those elements relatively to each other.

A bar or loop 20 is secured to the gimbal.

ring at a point above the tone-arm and substantially diametrically opposite the lug 12, and a spring arm 21. is fixed to and carried by the tone-arm member 18 and is provided 7 with a hooked end adapted to engage the bar when the tone-arm is raised to lock the tone-arm in raised position and to be yieldably disengaged therefrom when the tonearm is lowered to operativeposition. 7

Great advantage is attributed to the fact that the bent post 13 is secured to thehorizontallyswinging lug or projection 12, in that it allows of greater vertical movement ofthe tone-arm independently of the lug or rojection andits attached arm,whichwould be impossible, if the bent post 13 wasv affixed directly to the tone-arm, as the arm 14: attached to the post and extending under the turntable would preventthe raising of the tone-arm, as the arm would come in contact with the underside of the turn-table 4. With the bent post attached to the horizontal portion of a tone-arm, it wouldbe impossible to secure the necessary amount of vertical movement so asto retain'the tone arm in the proper raised ,POSltlOIl and out of contact with the record (lISC WhGH required.

Another advantage in having the bent post 13 secured to the lug12 is the fact that the action of the stop is'much more effective and positive than'a device in which the arm 14: is clamped to the tubular elbow portion 6; as in such a structure, the arm14 by reason of its clamping member which allows for relative movement in relation to the member 6, and by reason thereof, there is a tendency inthe device to be inaccurate.

\Vhereas with a device ,as herein described,

where the arm 14 isfafiixed directly to thehorizontally swinging lug 12 through the bent post 13, the action ismuch more effective and positive. I, i I l The operation of the device is obvious from the above description and accompany ingdrawings. v I In accordancewiththe provisions oflthe patent statutes, I have described the principle of my invention together with the apparatus which I now jconsider to represent the best embodiment thereof, but I desire it understood that my invention is not confined to the particular form of apparatus herein shown anddescribed, the same being merelyillustrative, and that the invention can be carried out in other ways without departing from the spirit of my invention, and, therefore, I claim broadly the right to em ploy all equivalent,instrumentalities coming within the scope of the appended claims, and by means of which objects of my invention are attained, and the new results accomplished, as herein set forth, as it is obvious that the particular embodiment herein shown and described is only one'of many that can be employed to attain these objects and accomplish these results.

Having now described my invention, what I claim and desire to secure by Letters Patent is as follows? 1.
